CROSS-REFERENCE

This application claims benefit of U.S. Provisional Application No. 62/184,813, filed on Jun. 25, 2015, U.S. Provisional Application No. 62/184,781, filed on Jun. 25, 2015, and U.S. Provisional Application No. 62/258,634, filed on Nov. 23, 2015, which are herein incorporated by reference in their entirety.

BACKGROUND OF THE INVENTION

Beta cells of the pancreas produce insulin, which is required for cells to take up glucose. Under normal conditions, blood glucose levels rise after eating, triggering pancreatic insulin release. However, in subjects with insulin dependent diabetes mellitus (type 1 diabetes (T1D)), beta cells are damaged by autoimmune inflammation, leading to an insufficiency of insulin. In contrast, subjects with non-insulin-dependent diabetes mellitus (type 2 diabetes (T2D)), have normal or high levels of insulin, but a resistance to insulin in peripheral tissues. Beta cells are not able increase secretion of insulin to overcome this resistance. Apoptosis of beta cells occurs in both type I and type II diabetes. Therapies for both T1D and T2D include those that require strict dietary regimens and/or drugs that are often not well tolerated long term, both of which make adherence to these therapies challenging for patients. Thus, additional and/or alternative therapies are desirable.

DETAILED DESCRIPTION OF THE INVENTION

Mammalian Sterile 20-like Kinase 1 (MST1) is upregulated in beta cells of islets in the pancreas that are exposed to a diabetogenic milieu, such as islets of type 2 diabetes patients and mice with mutant leptin receptors (db/db mice). Beta cell specific MST1 deficiency prevents loss of glucose regulation and beta cell mass induced by streptozotocin. MST1 mediates beta cell death via effects on mitochondria, pancreatic and duodenal homeobox 1 (PDX-1), and histone targets (see, e.g. FIG. 1). Therefore, MST1 inhibitors can serve as a therapeutic agent for patients with diabetes. In some embodiments, the MST1 inhibitor is neratinib.

Neratinib (also known as HKI-272) was identified as an inhibitor of MST1 kinase activity. Neratinib has been previously developed as an EGFR/HER-2 inhibitor, its use intended for breast cancer. Desirable pharmacokinetics and safety have been confirmed in human patients. However, neratinib as a modulator of MST1 and its use for treating diabetes, inflammatory conditions and autoimmune disorders is unprecedented.

Beta cell apoptosis was found to decrease with exposure to increasing concentrations of neratinib (see FIG. 3). Neratinib attenuated hyperglycemia in T1D model mice treated with streptozotocin (STZ) (see FIG. 4) and improved responses to acute glucose challenge in the T1D model mice (see FIG. 5). Neratinib reduced blood glucose and increased serum insulin in T1D model mice (see FIGS. 6-7).

Since diabetes is associated with and may be at least partially caused by autoimmune and inflammatory activity, the compounds described herein may have therapeutic potential for non-diabetes autoimmune and inflammatory conditions as well. In some embodiments, the MST1 inhibitor is neratinib.

Unless stated specifically in the specification, a substituted group may include one or more substituents selected from: oxo, amino, —CO₂H, nitrile, nitro, hydroxyl, thiooxy, alkyl, alkylene, alkoxy, aryl, cycloalkyl, heterocyclyl, heteroaryl, dialkylamines, arylamines, alkylarylamines, diarylamines, trialkylammonium (—N⁺R₃), N-oxides, imides, and enamines; a silicon atom in groups such as trialkylsilyl groups, dialkylarylsilyl groups, alkyldiarylsilyl groups, triarylsilyl groups, perfluoroalkyl or perfluoroalkoxy, for example, trifluoromethyl or trifluoromethoxy. “Substituted” also means any of the above groups in which one or more hydrogen atoms are replaced by a higher-order bond (e.g., a double- or triple-bond) to a heteroatom such as oxygen in oxo, carbonyl, carboxyl, and ester groups; and nitrogen in groups such as imines, oximes, hydrazones, and nitriles. For example, “substituted” includes any of the above groups in which one or more hydrogen atoms are replaced with —NH₂, —NR_(g)C(═O)NR_(g)R_(h), —NR_(g)C(═O)OR_(h), —NR_(g)SO₂R_(h), —OC(═O)NR_(g)R_(h), —OR_(g), —SR_(g), —SOR_(g), —SO₂R_(g), —OSO₂R_(g), —SO₂OR_(g), ═NSO₂R_(g), and —SO₂NR_(g)R_(h). In the foregoing, R_(g) and R_(h) are the same or different and independently hydrogen, alkyl, alkoxy, alkylamino, thioalkyl, aryl, aralkyl, cycloalkyl, cycloalkylalkyl, haloalkyl, heterocyclyl, N-heterocyclyl, heterocyclylalkyl, heteroaryl, N-heteroaryl and/or heteroarylalkyl. In addition, each of the foregoing substituents may also be optionally substituted with one or more of the above substituents. Furthermore, any of the above groups may be substituted to include one or more internal oxygen, sulfur, or nitrogen atoms. For example, an alkyl group may be substituted with one or more internal oxygen atoms to form an ether or polyether group. Similarly, an alkyl group may be substituted with one or more internal sulfur atoms to form a thioether, disulfide, etc.

The term “optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. For example, “optionally substituted alkyl” means either “alkyl” or “substituted alkyl” as defined above. Further, an optionally substituted group may be un-substituted (e.g., —CH₂CH₃), fully substituted (e.g., —CF₂CF₃), mono-substituted (e.g., —CH₂CH₂F) or substituted at a level anywhere in-between fully substituted and mono-substituted (e.g., —CH₂CHF₂, —CH₂CF₃, —CF₂CH₃, —CFHCHF₂, etc). It will be understood by those skilled in the art with respect to any group containing one or more substituents that such groups are not intended to introduce any substitution or substitution patterns (e.g., substituted alkyl includes optionally substituted cycloalkyl groups, which in turn are defined as including optionally substituted alkyl groups, potentially ad infinitum) that are sterically impractical and/or synthetically non-feasible. Thus, any substituents described should generally be understood as having a maximum molecular weight of about 1,000 daltons, and more typically, up to about 500 daltons.

An “effective amount” or “therapeutically effective amount” refers to an amount of a compound administered to a mammalian subject, either as a single dose or as part of a series of doses, which is effective to produce a desired therapeutic effect.

As used herein, MST1, a cleaved product thereof, a homolog thereof, a modification thereof (e.g. phosphorylation), complexes thereof, and a splice variant thereof, may be used interchangeably, unless otherwise specified. MST1, also known as Stk4, is a serine/threonine kinase. Homologs thereof may be selected from mammalian sterile 20-like kinase 2, Ste-20, and p21-activated kinase (Pak).

“Treatment” of an individual (e.g. a mammal, such as a human) or a cell is any type of intervention used in an attempt to alter the natural course of the individual or cell. In some embodiments, treatment includes administration of a pharmaceutical composition, subsequent to the initiation of a pathologic event or contact with an etiologic agent and includes stabilization of the condition (e.g., condition does not worsen) or alleviation of the condition. In other embodiments, treatment also includes prophylactic treatment (e.g., administration of a composition described herein when an individual is suspected to be suffering from a bacterial infection).

A “tautomer” refers to a proton shift from one atom of a molecule to another atom of the same molecule. The compounds presented herein may exist as tautomers. Tautomers are compounds that are interconvertible by migration of a hydrogen atom, accompanied by a switch of a single bond and adjacent double bond. In bonding arrangements where tautomerization is possible, a chemical equilibrium of the tautomers will exist. All tautomeric forms of the compounds disclosed herein are contemplated. The exact ratio of the tautomers depends on several factors, including temperature, solvent, and pH. Some examples of tautomeric interconversions include:

A “metabolite” of a compound disclosed herein is a derivative of that compound that is formed when the compound is metabolized. The term “active metabolite” refers to a biologically active derivative of a compound that is formed when the compound is metabolized. The term “metabolized,” as used herein, refers to the sum of the processes (including, but not limited to, hydrolysis reactions and reactions catalyzed by enzymes, such as, oxidation reactions) by which a particular substance is changed by an organism. Thus, enzymes may produce specific structural alterations to a compound. For example, cytochrome P450 catalyzes a variety of oxidative and reductive reactions while uridine diphosphate glucuronyl transferases catalyze the transfer of an activated glucuronic-acid molecule to aromatic alcohols, aliphatic alcohols, carboxylic acids, amines and free sulfhydryl groups. Further information on metabolism may be obtained from The Pharmacological Basis of Therapeutics, 9th Edition, McGraw-Hill (1996). Metabolites of the compounds disclosed herein can be identified either by administration of compounds to a host and analysis of tissue samples from the host, or by incubation of compounds with hepatic cells in vitro and analysis of the resulting compounds. Both methods are well known in the art. In some embodiments, metabolites of a compound are formed by oxidative processes and correspond to the corresponding hydroxy-containing compound. In some embodiments, a compound is metabolized to pharmacologically active metabolites.

Methods of Dosing

For certain embodiments, the compositions containing the compound(s) described herein are administered for prophylactic and/or therapeutic treatments. In certain therapeutic applications, the compositions are administered to a patient already suffering from a disease or condition, in an amount sufficient to cure or at least partially arrest at least one of the symptoms of the disease or condition. Amounts effective for this use depend on the severity and course of the disease or condition, previous therapy, the patient's health status, weight, and response to the drugs, and the judgment of the treating physician. Therapeutically effective amounts are optionally determined by methods including, but not limited to, a dose escalation clinical trial.

In prophylactic applications, compositions containing the compounds described herein are administered to a patient susceptible to or otherwise at risk of a particular disease, disorder or condition. Such an amount is defined to be a “prophylactically effective amount or dose.” In this use, the precise amounts also depend on the patient's state of health, weight, and the like. When used in a patient, effective amounts for this use will depend on the severity and course of the disease, disorder or condition, previous therapy, the patient's health status and response to the drugs, and the judgment of the treating physician. In one aspect, prophylactic treatments include administering to a mammal, who previously experienced at least one symptom of the disease being treated and is currently in remission, a pharmaceutical composition comprising a compound of Formula (I), (Ia), (Ib), (II), (IIa), or (IIb) in order to prevent a return of the symptoms of the disease or condition.

In certain embodiments wherein the patient's condition does not improve, upon the doctor's discretion the administration of the compound of Formula (I), (Ia), (Ib), (II), (IIa), or (IIb) is administered chronically, that is, for an extended period of time, including throughout the duration of the patient's life in order to ameliorate or otherwise control or limit the symptoms of the patient's disease or condition.

In certain embodiments wherein a patient's status does improve, the dose of drug being administered may be temporarily reduced or temporarily suspended for a certain length of time (i.e., a “drug holiday”). In specific embodiments, the length of the drug holiday is between 2 days and 1 year, including by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, or more than 28 days. The dose reduction during a drug holiday is, by way of example only, by 10%-100%, including by way of example only 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, and 100%.

In certain embodiments the dose of drug being administered may be temporarily reduced or temporarily suspended for a certain length of time (i.e., a “drug diversion”). In specific embodiments, the length of the drug diversion is between 2 days and 1 year, including by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, or more than 28 days. The dose reduction during a drug diversion is, by way of example only, by 10%-100%, including by way of example only 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, and 100%. After a suitable length of time, the normal dosing schedule is optionally reinstated.

In some embodiments, once improvement of the patient's conditions has occurred, a maintenance dose is administered if necessary. Subsequently, in specific embodiments, the dosage or the frequency of administration, or both, is reduced, as a function of the symptoms, to a level at which the improved disease, disorder or condition is retained. In certain embodiments, however, the patient requires intermittent treatment on a long-term basis upon any recurrence of symptoms.

The amount of a given agent that corresponds to such an amount varies depending upon factors such as the particular compound, disease condition and its severity, the identity (e.g., weight, sex) of the subject or host in need of treatment, but can nevertheless be determined according to the particular circumstances surrounding the case, including, e.g., the specific agent being administered, the route of administration, the condition being treated, and the subject or host being treated. In general, however, doses employed for adult human treatment are typically in the range of 0.01 mg-5000 mg per day. In one aspect, doses employed for adult human treatment are from about 1 mg to about 1000 mg per day. In one embodiment, the desired dose is conveniently presented in a single dose or in divided doses administered simultaneously (or over a short period of time) or at appropriate intervals, for example as two, three, four or more sub-doses per day.

In some embodiments, as a patient is started on a regimen of an antiviral compound, the patient is also weaned off (e.g., step-wise decrease in dose) a second treatment regimen.

In one embodiment, the daily dosages appropriate for a compound of Formula (I), (Ia), (Ib), (II), (IIa), or (IIb) described herein are from about 0.01 to about 10 mg/kg per body weight. In specific embodiments, an indicated daily dosage in a large mammal, including, but not limited to, humans, is in the range from about 0.5 mg to about 1000 mg, conveniently administered in divided doses, including, but not limited to, up to four times a day. In one embodiment, the daily dosage is administered in extended release form. In certain embodiments, suitable unit dosage forms for oral administration comprise from about 1 to 500 mg active ingredient. In other embodiments, the daily dosage or the amount of active in the dosage form are lower or higher than the ranges indicated herein, based on a number of variables in regard to an individual treatment regime. In various embodiments, the daily and unit dosages are altered depending on a number of variables including, but not limited to, the activity of the compound used, the disease or condition to be treated, the mode of administration, the requirements of the individual subject, the severity of the disease or condition being treated, and the judgment of the practitioner.

Toxicity and therapeutic efficacy of such therapeutic regimens are determined by standard pharmaceutical procedures in cell cultures or experimental animals, including, but not limited to, the determination of the LD₅₀ and the ED₅₀. The dose ratio between the toxic and therapeutic effects is the therapeutic index and it is expressed as the ratio between LD₅₀ and ED₅₀. In certain embodiments, the data obtained from cell culture assays and animal studies are used in formulating the therapeutically effective daily dosage range and/or the therapeutically effective unit dosage amount for use in mammals, including humans. In some embodiments, the daily dosage amount of the compounds described herein lies within a range of circulating concentrations that include the ED₅₀ with minimal toxicity. In certain embodiments, the daily dosage range and/or the unit dosage amount varies within this range depending upon the dosage form employed and the route of administration utilized.

Example 1: Synthesis of N-(4-chloro-3-cyano-7-ethoxyquinolin-6-yl)-4-(dimethylamino)butanamide (5)

Step 1: 6-Amino-4-chloro-7-ethoxyquinoline-3-carbonitrile (2)

N-(4-Chloro-3-cyano-7-ethoxyquinolin-6-yl)acetamide (1) (1.53 g, 5.27 mmol) was suspended and stirred in 10 mL of water and the reaction flask was placed in a 0° C. ice-water bath. Concentrated HCl (15 mL) was added dropwise with stirring over 10 min. The reaction flask was placed in a 50° C. oil bath and reaction progress was monitored by LCMS until ˜90% conversion, at which point competing byproducts began to appear as observed by LCMS. The reaction was stirred in a 0° C. ice-water bath and was quenched with saturated NaHCO₃. The product was extracted into EtOAc and evaporated to dryness. The crude product (1.2 g of ˜85:15 product: starting material, ˜4.85 mmol) was taken on to the next step without further purification.

Step 2: N-(4-chloro-3-cyano-7-ethoxyquinolin-6-yl)-4-(dimethylamino)butanamide (3)

4-(Dimethylamino)butanoic acid hydrochloride (1.95 g, 11.6 mmol) was suspended in EtOAc (20 mL) and DMF (0.08 mL, 1.0 mmol) under argon in a 0° C. ice-water bath. Oxalyl chloride (0.870 mL, 10.2 mmol) was added dropwise over 5 minutes and the suspension was stirred in the ice-water bath for 20 minutes. The bath was removed and the reaction was allowed to stir at ambient temperature for 2 h then was placed into a 0 OC ice-water bath. A solution of 2 (1.20 g, 4.85 mmol) in NMP was then added and the reaction was allowed to stir in the ice-water bath for 90 minutes. The reaction was quenched by the addition of water (40 mL), washed with EtOAc (50 mL) and the organic layer was extracted with 1 N HCl (30 mL). The combined aqueous layers were basified to pH 11 with 10 N NaOH to precipitate the product. The product (1.118 g) was collected via filtration as a yellow solid and was used in the next step without purification. NMR shows >90% purity. ¹H NMR (400 MHz, Methanol-d₄) δ 9.16 (s, 1H), 8.83 (s, 1H), 7.49 (s, 1H), 4.39 (q, J=6.9 Hz, 2H), 2.61 (t, J=7.3 Hz, 2H), 2.52-2.43 (m, 2H), 2.32 (s, 6H), 1.95 (p, J=7.5 Hz, 2H), 1.58 (t, J=7.0 Hz, 3H).

Step 3: 3-chloro-4-((3-methylpyridin-2-yl)methoxy)aniline (4)

4-Amino-2-chlorophenol (72 mg, 0.50 mmol), 2-(chloromethyl)-3-methylpyridine (100 mg, 0.56 mmol) and cesium carbonate (0.82 g, 2.5 mmol) were stirred in acetonitrile (2.5 mmol) at ambient temperature overnight. [Note: when chloromethyl-substituted heterocycles were not available, the chloride was formed from the alcohol and SOCl₂]. The suspension was filtered and evaporated to dryness before being purified by gradient flash chromatography (0 to 100% EtOAc in hexanes with 0.1% trimethylamine). The major peak by UV was collected and its identity was checked on LCMS to ensure it was the desired product; m/z of 249.1 (M+1+) was observed. This product was taken to the next step without further characterization.

Step 4: N-(4-chloro-3-cyano-7-ethoxyquinolin-6-yl)-4-(dimethylamino)butanamide (5)

Compound 3 (18 mg, 0.05 mmol), pyridine-hydrochloride (6 mg, 0.05 mmol) and Compound 4 (12.5 mg, 0.05 mmol) were stirred in isopropanol (0.5 mL) in a heating block at 75° C. for 16 h. After cooling to ambient temperature, the reaction mixture was diluted with MeOH to dissolve all components and purified by preparative HPLC to yield the product (5, 7.23 mg) as the bis-TFA salt. ¹H NMR (400 MHz, Methanol-d4) δ 9.09 (s, 1H), 8.77 (s, 1H), 8.49 (d, J=5.2 Hz, 1H), 7.98 (d, J=7.9 Hz, 1H), 7.59-7.53 (m, 2H), 7.44-7.34 (m, 3H), 5.44 (s, 2H), 4.40 (q, J=7.0 Hz, 2H), 3.29-3.20 (m, 2H), 2.93 (s, 6H), 2.74 (t, J=6.9 Hz, 2H), 2.55 (s, 3H), 2.12 (dt, J=15.2, 7.1 Hz, 2H), 1.59 (t, J=7.0 Hz, 3H); MS-ESI (m/z) calcd for [C₃₁H₃₃ClN₆O₃+H]⁺573.24; found: 573.24.
